When trying to write a user to the database I am getting errors in my console?

When trying to write a new user to the mongo db i am getting an error when trying to save them to the database i have logged the incoming requests to the console and they all are working properly. If someone could take a look at my code and see what the problem is that would be awesome! Thanks in advance!

app.js

const express = require("express");
const cors = require ("cors");
const passport = require("passport");
const bodyParser = require("body-parser");
const  mongoose  = require("mongoose");
const User = require('./models/user');






var app = express();
app.use(express.json());
app.use(express.urlencoded({extended: true}));
app.use(bodyParser.json());
app.use(cors());
app.use(passport.initialize());
mongoose.connect(process.env.MONGO_URI, (err,res)=>{
    if(err){
        console.log("not connected to mongo")
    }else{
        console.log("connection successful")
    }
})


app.post("/user/signup", (res,res)=>{
    let newUser = new User({
        firstName: req.body.firstName,
        lastName: req.body.lastName,
        email: req.body.email
    })
    newUser.save()
})






app.listen( 8080, () =>{
    console.log(`Server is listening on port: 8080`)
})

mongoose model:

const mongoose = require('mongoose');


new userSchema = new mongoose.Schema({
    firstName: string,
    lastName: string,
    email: string
})


module.exports = (userSchema)

console.log when starting server:

const mongoose = require('mongoose'); new userSchema = new mongoose.Schema({ firstName: string, lastName: string, email: string }); module.exports = mongoose.model('user',userSchema)

//add this import const { json } = require("body-parser"); app.post("/user/signup", (res,res)=>{ let newUser = new User({ firstName: req.body.firstName, lastName: req.body.lastName, email: req.body.email }) newUser.save() .then(result => { res.json({ result: result }); }) .catch(err => { res.json({ error: err }); }); });

Hello Codeinger123! I believe the reason for the error is because fist of all when you create a mongoose schema you should use syntax like this:

And also when when you save a mongo document it creates a promise which in the code snippet above you are not providing a callback for. Try something like this:

Try this out and let me know if you are still getting an error or if it works.
